Smart inventory
Every purchase becomes a batch with its cost and date, and the oldest gets used first. Out of stock? The app warns you, lets you keep going and squares things up on your next purchase.
Guided production
Six steps from planning to done: one combined list of materials to gather, the piece step by step, weighing, overheads and time.
Shopping lists
Build your list from what you are about to make: the app adds up everything the recipes call for. Check items off at the store, close it out with what you paid and share it as text or PDF.
Sales
Product, quantity and how you got paid. Every sale shows what you really made.
Calendar and alerts
Scheduled production, deliveries, payments due and quotes about to expire, day by day. The bell flags missing items, products without a price, negative stock and overdue payments. Phone reminders are optional.
Your brand on the PDFs
Add your logo and business details once, and every quote, order, list and report goes out with your header, ready to send.

Frequently asked questions
How do I price a crochet piece?
Add up the cost of each material in the quantity the composition uses, plus the packaging, and divide by the yield: 2 beanies give you the cost of one. The price comes from that cost plus fees and the margin you want; your hourly rate goes into the production when you turn the switch on. Custí runs the same math, with the cost of your last purchase.
Is Custí only for food?
No. On the first screen you say what you make, and the app speaks your trade: raw materials and formulas for cosmetics and candles, materials and compositions for crafts, recipes and batches for cooks. The math is the same for everyone.
Do I have to pay to start?
No. The free plan lets you register what you buy and what you make, see the cost and calculate the selling price, plus customers and PDF quotes. Production, inventory, sales, orders and reports are Premium, with 7 days to try it.
